We're dividing 66158472 by 980 
We want to figure out the number of times 66158472 can be divided by 980.

Advancing to step 1:
If we divide 6 by 980, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 980

Advancing to step 2:
The number 980 fits into 66 0 times, leaving a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Include the next digit (1) from the dividend after 66, then repeat: 661 / 980

Step 3:
661 divided by 980 is 0 with a remainder of 661.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 661 to get 661.
Take the next digit (5) from the dividend and append it to 661, then repeat: 6615 / 980

On to step 4:
6615 divided by 980 is 6 with a remainder of 735.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 5880 away from 6615, we end up with 735.
Take the next digit (8) from the dividend and append it to 735, then repeat: 7358 / 980

Let's proceed to step 5:
980 can be fit into 7358 7 times, resulting in a remainder of 498.
The number 7 becomes the next digit in our result. 
Result so far: 67.0
Deduct 6860 from 7358 and we're left with 498.
Take the next digit (4) from the dividend and append it to 498, then repeat: 4984 / 980

Step 6:
980 can be fit into 4984 5 times, resulting in a remainder of 84.
Put 5 as the next digit of the answer. 
Result so far: 675.0
The remainder is 84 after subtracting 4900 from 4984.
Take the next digit (7) from the dividend and append it to 84, then repeat: 847 / 980

Advancing to step 7:
980 goes into 847 0 times with a remainder of 847.
Record the quotient 0 as the next digit in the result. 
Result so far: 6750.0
If we take 0 away from 847, we end up with 847.
Grab the next digit (2) from the dividend, add it to 847, then carry on: 8472 / 980

Let's proceed to step 8:
980 goes into 8472 8 times with a remainder of 632.
Write down 8 as next digit of the result. 
Result so far: 67508.0
If we subtract 7840 from 8472, we get 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

Advancing to step 9:
The number 980 fits into 6320 6 times, leaving a remainder of 440.
Record the quotient 6 as the next digit in the result. 
Result so far: 67508.6
Deduct 5880 from 6320 and we're left with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

On to step 10:
When dividing 4400 by 980, we get 4 with a remainder of 480.
The next digit of our result is 4. 
Result so far: 67508.64
If we subtract 3920 from 4400, we get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Let's proceed to step 11:
980 goes into 4800 4 times with a remainder of 880.
Write down 4 as next digit of the result. 
Result so far: 67508.644
Subtracting 3920 from 4800 leaves us with 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8800, and continue the process.

The final outcome is 67508.644, with a leftover of 0.088.
